Can I duplicate a mesh along curves if the curves have been moved?
I've noticed that when I apply scale to a curve that is used as a curve modifier by an object, this object always get bigger/smaller, so I guess the solution is either not to apply scale to the curve you use (or to only work its shape in edit mode which is even preferable as you will always stay at its original scale), or to scale it again and apply scale until the object is at its correct size, but this is not the good solution.
